| What it's not: |

| What it is: |
A zygote is a fertilized egg before cell division starts to form it into an embryo. The result of the successful union of a haploid egg and sperm, a human zygote is a diploid cell with 46 chromosomes. We human beings all started out as zygotes, (but not all zygotes are human beings, of course). |
